Pierre-Emerick Aubameyang and Alex Lacazette found the net as we grafted our way to victory over a resolute Cardiff side.
Aubameyang’s 18th goal of the season came from the penalty spot, but he owed a debt of gratitude to Alex Iwobi, whose perfect pass sent Sead Kolasinac into the box. The Bosnian went down under a mistimed challenge from Bruno Ecuele Manga.
Aubameyang did the rest - to the relief of an increasingly anxious home crowd.
Lacazette gave us a two-goal cushion with a powerful low finish after a barnstorming run into the box. And we held on to the points despite a stoppage-time strike from Nathaniel Mendez-Liang.
